Hello Andreas,

I'm not (totally) sure about this as i already tried to compile Nagios
and NDOUtils with SUN-Studio compilers (Studio 11 for Solaris 8) and
get the same results.

Maybe you remember one of my last mails (from April this year)...

this is what i did:

1. add the following to include/config.h (for ndoutils):
#ifndef SUN_LEN
#define SUN_LEN(sunp) ((size_t)((struct sockaddr_un *)0)->sun_path + =
strlen((sunp)->sun_path))
#endif

2. add the following file to src (and add it to the makefile) to get =
"strtof":
bash-2.03# cat strtof.c
#include
#include
#include

float strtof(const char* s, char** endptr) {
register const char* p =3D s;
register float value =3D 0.;
int sign =3D +1;
float factor;
unsigned int expo;

while ( isspace(*p) )
p++;

switch (*p) {
case '-': sign =3D -1;
case '+': p++;
default : break;
}

while ( (unsigned int)(*p - '0') >=3D 1) =3D=3D 0 )
break;
factor *=3D factor;
}
}

done:
if ( endptr !=3D NULL )
*endptr =3D (char*)p;

return value * sign;
}


any ideas more? especially.... is my definition for SUN_LEN correct?
and... does anybody have a (maybe) better "strtof" for Solaris 8 ?

Thanks again!
Christian
